Answer:
The words act as a context clue to point out the relationship between the two men's attitudes are D: even though... he himself
Step-by-step explanation:
Context clues are suggestions that an author uses in his writing to help define an unusual word within a book.
Option D is the context clue that brings out the relationship between the two men's attitudes because these words highlight the fact that the two men, Fred and George, have opposing views.
“Even though” means Fed thinks something about George and “he himself” which is used for George, is supporting industrial expansion. Other options, “Support” and “Generously” do not show any relationship between the views. “Advocate of industrial expansion” doesn’t show any relationship between the attitude of two men.
